The brands.twig view will display all of the brands that have been configured in the account.

In most circumstances the brands page will extend the collection.twig template because it's format will follow the usual display of collection pages on your theme.

The brands page has access to the brand object which can be used to display details of each brand (such as the brand name and image) with a link through to the brand page, e.g.

{% for brand in brands %}
    {{ brand.title }}
{% endfor %}
